First Peptide Cycle Checklist

A non-prescriptive checklist for first-cycle peptide research: safety, supplies, math, tracking, and stop signs.

What should I check before a first peptide cycle?

Before a first peptide cycle, know what you are using, why you are using it, what would make you stop, how the vial math works, and what you will track. If any of those answers are vague, slow down.

Before the first dose

  • Read the compound page, not just a social post.
  • Check contraindications and medication conflicts.
  • Understand the route: sub-q, IM, nasal, oral, or topical.
  • Run vial size, BAC water, and target dose through the calculator.
  • Have supplies ready before the vial is mixed.

Tracking

  • Log date, dose, time, and injection site.
  • Track the outcome you care about, not just the dose.
  • Write down side effects while they are fresh.

Stop signs

Severe allergic symptoms, persistent worsening side effects, contaminated-looking vial contents, or a contraindication you missed are reasons to stop and get qualified medical guidance.

Pepdex is an educational reference, not medical advice. Peptides vary in legal, approval, and evidence status. This answer is meant to explain the concept, not prescribe a protocol or replace a qualified clinician.
